Just found that http://grouppatternlanguage.org/wagn/Storytelling+related_patterns had its permissions set to "Anyone signed in" to read or comment. Reminded me i'd seen the same thing yesterday on http://grouppatternlanguage.org/wagn/Hosting and all of its plus cards. Vague memory of earlier similar if not identical behavior, perhaps on other Wagns, so creating this ticket to note it and collect other examples if they arise.

I've fixed all the examples cited above; let me know if you want any new ones left as-is if that will help figuring this out.
